  • Apparatus for testing molten metal
    Patent number: 4003260
    Abstract: A measuring or sampling probe is to be lowered to a desired depth in a molten metal. The probe is mounted on a probe carrier which can be lowered and raised. A contact detector, which emits a control signal when the detector comes into contact with the upper surface of the molten metal, is fixed on the probe carrier at a distance above the probe.

  • Introduction of a liquid into a receptacle such as a converter
    Patent number: 3997334
    Abstract: A liquid fuel or other liquid is supplied to a supply line which communicates with an injection conduit opening out into a receptacle such as a steelmaking converter. The supply line includes a non-return valve which allows the liquid to pass only when its pressure exceeds a given critical pressure. A gas is introduced into the supply line downstream of the non-return valve at a pressure which is hgher than the critical pressure and which is sufficient to prevent any material in the receptacle from penetrating into the injection conduit.

  • Agglomeration of ore by sintering
    Patent number: 3984230
    Abstract: A combustible bed of ore is formed on a sinter grate, which may form part of a sinter strand. Holes are pierced through the bed before ignition. Combustion-supporting gas is passed through the ignited bed to cause a combustion front to pass through the bed. The bed can be pierced by piercing members carried by a reciprocal frame on a carriage moving parallel to the sinter strand.

  • Apparatus for determining the properties of metallic materials
    Patent number: 3948091
    Abstract: The apparatus includes a machine for subjecting a test-piece of superplastic material to a tensile test using a mobile member entraining one end of the test-piece and exerting traction on the test-piece. The mobile member is subjected to successive displacements whose speed and duration are controlled. The force applied to the test-piece and its length are measured as a function of time.
